Strong disagree on using a database as a message queue. This article[0] covers many of the reasons why. Summary: additional application complexity and doesn't scale well with workers.

I'm increasingly of the opinion that relational databases are absolutely the right way to build queue systems for most projects.

One of the biggest advantages comes when you start thinking about them in terms of transactions. Transactional guarantees are really useful here: guarantee that a message will be written to the queue if the transaction commits successfully, and guarantee that a message will NOT be written to the queue otherwise.

https://brandur.org/job-drain describes a great pattern for achieving that using PostgreSQL transactions.
